Laser skin resurfacing, also known as laser
peel or laser lasabrasion, is a procedure using laser beams to reduce certain skin imperfections
such as wrinkles, pigment spots, scars and blemishes.
The skin is composed of three layers: epidermis (the outermost), dermis and hypodermis. The
dermis contains bundles of well organized collagen fibers which contribute to the firmness
and smoothness of the skin. As the skin gets older, these fibers become less in number
and also less organized, wrinkles and age spots appear.
Laser beams destroy the outer layer of the skin removing unwanted wrinkles and spots.
At the same time, the heat of the beams stimulates the growth of collagen fibers in the dermis.
As the wound is healing, new skin that grows over it is smoother and firmer.
The classic laser skin resurfacing uses laser to ablate a large area of the problematic
skin. The whole problem, such as a dark spot, is removed in one treatment, but as the burned-out
area is large, it takes a long time to heal and is subject to higher risk of infection.
The newer technique – fractional laser skin resurfacing – uses multiple smaller laser
beams to ablate the skin in smaller spots, leaving undamaged skin tissue in between.
This makes the healing faster and less complicated. However, a series of treatments is needed
to achieve desirable results.
